I was just now about to ask everyone how to do something with the Materials Lab and the Texture Library, but I was able to solve it on my own. However, now there's another question that has come up:

In the Materials Lab, I have a material which does not have a bump map, and I need it to have one. How can I create a bump map to a material which does not have one?

It's not a picture type of material.. I mean I can't get into the Leo thing to apply a picture for the bump. I'm not sure how to call this type of material... procedural maybe? Anyway, here's a screen capture of what I'm working with if it'll be of any help. The material in question is the one in slot B, "caustic a17".
